A quiet blower fan kit designed to boost airflow coming from your home’s fireplace. Suitable for fireplaces with space underneath its floor or compartment to install the blower. The system draws cool air in from the bottom vents, heats it through the fireplace, then forcing it out the top vent into the room. Being a standard size, it can also replace existing blowers found in various fireplaces including Lennox, Hearth Glo, Majestic, Rotom, and more. The system features a LCD display with smart thermostat and humidity programming. Included corded sensor plugs into the controller to provide temperature and humidity readings. Heavy-duty build includes a cold-rolled steel mounting frame. Features PWM-controlled motor that is highly efficient in maximizing airflow at lower noise. Includes everything needed to secure the unit and power it through an outlet. The controller included with each unit features active temperature and humidity monitoring. Fan speeds can be programmed to automatically adjust to high and low temperatures and humidity. The program can also be manually set the fans to run continuously or on a timer at custom speeds. Also features alarm warnings, fan failure alerts, eco-mode, and backup memory. Includes a 12-foot corded sensor probe. The fan system is enclosed in heavy-duty steel mounted on a cold rolled steel frame. The aluminium impeller is suspended in mid-air with silicone mounts to absorb vibrations and to reduce noise. Utilizing DC motors that are controlled using PWM (Pulse Width Modulation), the blower can maximize airflow while reducing noise and power consumption. In addition, the blower is IP-22 rated to be resistant to liquids and dust particles. The motor houses dual-ball bearings rated at 67,000 hours and are certified by CE and RoHS.
